Abstract:
Objective:To evaluate the value of color Doppler ultrasonography in diagnosing primary squamous cell carcinoma of the thyroid(PSCCT).Methods:Ultrasound images of 13 patients from August 2010 to June 2019 in the Second Hospital of Hebei Medical University with PSCCT confirmed by surgery and pathology were analyzed retrospectively.The ultrasonographic features were summarized.Results:All of the cases were single lesion. 92.3%(12/13) of the lesions were hypoechoic on ultrasound, 69.2%(9/13) of the lesions were ≥5 cm in maximal dimension and occupied one lobe of the thyroid gland, 76.9%(10/13) of the lesions were irregular, 69.2%(9/13) of the lesions had unclear boundary, 61.5%(8/13) of the lesions broke through the thyroid capsule and showed invasive growth. Calcification was rare, 23.1%(3/13) of the lesions were accompanied by striated calcification, 7.7%(1/13) of the lesions were accompanied by eggshell calcification, 15.4%(2/13) of the lesions showed few blood flow, 53.8%(7/13) of the lesions showed moderate blood flow, 30.8%(4/13) of the lesions showed rich blood flow, 69.2%(9/13) of the lesions were detected higher vascular resistance spectrum, 53.8%(7/13) of the lesions exhibited cervical metastatic lymph nodes. The ultrasonographic features of metastatic lymph nodes were hypoechoic, the lymphatic hilum structures were absent, with cystic changes in the interior.Conclusions:The color Doppler ultrasound images of PSCCT have certain specific features, and the identification of its sonographic characteristics is helpful to improve the diagnosing level of PSCCT.
